BARBED-METAL-STRIP FENCING.

SPECIFICATION forming part of Letters Patent No. 307,005, dated October21, 1884.

Application filed May 15, 1882. (N0 model.)

and the supporting or re-enforce piece being upon the opposite side ofthe section from that I shown in the drawings. Fig. 2 representsa Viewof the opposite side of the section shown in Fig. 1. Fig. 7 represents across-section taken on line a a, Fig. 2, looking in the direction of thearrow, same figure. Figs. 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14,15, 16,17, 18, 19, 20, 21,22, 23, 24, 25, 26, and 27 represent modifications ofmy improved barbed-metalstrip fencing, as will be fully describedhereinai'ter.

The present invention consists in a metal fencing in which a thin metalstrip is re-enforced by a re-enforcing piece, and the barbs have partslooped or bent around both said strip and re-enforcing piece to unitethem firmly together.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it more in detail.

In the drawings, the part marked A represents a strip of thin metal ofany Suitable kind. The part marked B represents the reenforoe piece,used in combination with the strip A in the manner to be hereinafter.described. The parts marked 0 represent barbs, which may be made ofsheet metal or strips, with their ends pointed, and may be made in theshapes or of the forms shown in the drawings, or other similar shapes,without departing from the principle of my invention.

In Figs. 1, 2, and 7 of the drawings the reenforce piece B is made ofwire placed zigzag upon the strip A, and upon the same side of saidstrip as the barbs O are placed. Said barbs have each two lugs or cars,D, bent one over the top and the other under the bottom of strip A. Oneof these parts D on each barb is formed into a loop on the same side ofstrip A as the-main portion of the barb itself, and through this loopthe re-enforce wire D passes. By this construction strip A and wire Bare firmly secured together, and the barb C is likewise prevented fromslipping.

In Figs. 3, 4., and 8 of the drawings the reenforce piece B is placedupon the opposite side of the strip from that shown'in Figs. 1, 2, and7, so that the barbs will be upon one side of the strip and there-enforce piece or wireB 'upon the other, as shown in the drawings, the're-enforce piece being held in place upon the stripby bending over thesame one of the lugs or cars D of the barb O, as fully Shown in Fig. 8of the drawings, and the barb 0 being retained' in place and preventedfrom slipping or moving upon the strip A by thus bending the lug D overthe re-enforce piece B at the points 0 where the re-enforce piece isbent.

In Figs. 5, 6, and 9 of the drawings the reenforce piece B is made of athin strip of metal, and the barb G is held in place upon the strip A bybending the barbs, so as to encircle said strip A, and inserting theends through holes or openings in the re-enforce piece B, and thenbending them over, so as to extend out in opposite directions, thusholding and retaining 8o securely in place upon the strip A the barb G,as fully shown in Fig. 9 of the drawings, and preventing any motion ofbarb 0 upon the fencing-strip A.

In Figs. 10, 11, and 12 the strip A, re-enforce piece B, and barbs O arecombined to-- gether by placing the barbs between the strip A andre-enforce piece B and inserting the lugs or cars D of the barbs 0through slots or openings in the re-enforce piece B, and then 0 bendingthem over the edges of the strip A, so that their ends will be upon theopposite side of the said strip A from the re-enforce piece B, as fullyshown in Fig. 12 of the drawings, and thus in this modification there-en- 5 force strip B serves to retain the barbs 0 se curely in placeupon the fencing-strip A.

The construction of the fencing shown in Figs. 13, 14, and differs fromthat shown in Figs. 5, 6, and 9 only in that asheet-metal barb, G, issubstituted for the wire barb G, the ends of said sheet-metal barb beinginserted through aslot, E, in the re-enforce piece B, and then bent out,as fully shown in Fig. 15 of the drawings, the re-enforce piece Bretaining the barb C in place upon the fencing-strip A in the samemanner as in Figs. 5, 6, and 9.

In Figs. 16, 17, and 18 the re-enforce piece 13 is placed between thestrip A and the barb G, and said barb G is retained in place andprevented from slipping upon the strip A by making cuts upon the edgesof re-enforce piece 13 upon each side of the barb G, and then bendingthem up, so as to form small projections H on each side of the barb O,as fully shown in Fig. 16 of the drawings. The lugs D are bent over uponthe other side of the strip A, as shown in Fig. 17, and the barb G isthus, by means of the re-enforce piece B, as described, retained inplace upon the strip-fencing A.

In Figs. 19, 20, and 21 the barb (J is placed between the strip A andre-enforce piece B. Said barb is held in place upon said strip A byinserting through holes or openings F in the re-enforce piece B thepointed lugs D, cut from barb C, and pressing or bending them over, asshown in Fig. 19, and the lugs D are also bent over and pressed down, asshown in Fig. 20 of the drawings, upon the opposite side of the strip A.Thus the barb is held securely in place and prevented from slipping uponthe fencing-strip A. i

In Figs. 22, 23, and 24 the re-enforce piece B is provided with twolongitudinal slots or cuts, G, through which the barb G is inserted, as

shown in Fig. 22, and then the lugs D bent over the edges of strip A, asshown in Fig. 23 of the drawings, so that the barbs are secured firmlyupon the fencing-strip A and prevented from moving.

The fencing shown in Figs. 25, 26, and 27 is constructed in the same wayas that shown in Figs. 10, 11, and 12, the barb Cbeingretained in placeupon the strip A by inserting the lugs I) through slots or cuts in there-enforce piece 13 and then bending them over the edges of strip A, asshown in the drawings; but the shape of the barb is different from thatshown in Figs. 10, 11, and 12.

In my application of even date herewith, serially numbered 61,451, Ihave set forth and specifically claimed a barbedstrip fencing comprisinga metal strip, are-enforcing wire, and barbs, the latter havinga centralloop encircling the wire, and having its ends passed through the stripand bent in opposite directions. Such constru ction,therelore, is notspecifically claimed herein.

Having described my improvements in barbed fencing, what I claim thereinas new and of my invention, and desire to secure by Letters Patent, is

A barbed-metal fencing comprising a thin strip of metal, a re-enforcingpiece, and barbs, the latter having portions bent or looped around boththe former, so as to fasten the two firmly together, substantially asdescribed.
